Sorry, no winner this week. Here is my weekly weather quiz question for the last time. How many “active” volcanoes are there in the world? Here is the correct answer. The answer to this common question depends upon use of the word “active.” At least 20 volcanoes will probably be erupting as you read these words (Italy’s Stromboli, for example, has been erupting for more than a thousand years); roughly 60 erupted each year through the 1990s; 154 in the full decade 1990-1999; about 550 have had historically documented eruptions; about 1300 (and perhaps more than 1500) have erupted in the Holocene (past 10,000 years); and some estimates of young seafloor volcanoes exceed a million. For more details go to The Global Vulcanism Program website. I’ll have a new weekly weather quiz question for you starting Monday. Please remember to post your answer as a comment by clicking on “no comments /comments” in the upper right hand portion of this page under the caption, then add your comment. The first person to post the correct answer will win a week of free personalized weather forecasts tailored to your needs. The answer has to be a comment to win. An email answer will not count.

Advisories: NONE AT THIS TIME.

An upper level low (the shaded”U” shape on the jet stream) pushed a frontal system through the Pacific Northwest Friday, returning the clouds and the chance of rain and lowering mountain snow levels down to the passes. This storm could produce the first snowfall of the season at pass levels.
